The difference between muesli and granola is that granola is baked. Invented by the American, James Jackson in 1863 under the name Granula, it was then adopted by John Kellog, who created his own version called Granola. Granola is now such a popular breakfast that it is no longer considered a trademark, and just the name for this particular type of cereal.

What's so wonderful about making it yourself is that you can heat it warm, straight from the oven.
